Dragonball Evolution - I was a kid and a huge DBZ fan and it was absolutely unbelievable for me that they were making a dragonball movie. Hated the movie as a kid, absolutely loathe the movie now.

That movie has literally no moment of enjoyment or happiness or nostalgia and makes Goku look like an absolute idiot. Goku was supposed to be my childhood hero and a character which would really inspire. This is a legit example when an adaptation is said to have destroyed someone's childhood memories. To the people who allowed this piece of shit to surface: Fuck you!
